GASOLINE-DISPENSING APPARATUS Applieaiien mea December 9,' 1924. serial No. 754,866.

The principal objects of the invention are to effect an instantaneous automatic refilling of the measuring bowl following the dispensing of a quantity of the gasoline therefrom, thereby elfecting aisa'ving of time and ensuring a greater rapidity of service.

A further object is to entirely eliminate waste in handling the gasoline thereby effecting a direct saving and also eliminating the danger of fire as all overflow is returned to the main supply.

The principal feature of the invention consists in the novel construction and arrangement of parts, whereby the control of the supply of gasoline to the measuring bowl is governed automatically by the manipulation of the dispensing tube. f

In the drawings, Figure 1 is a perspective view of a dispensing apparatus showing the arrangement of the measuring standard and supply tanks.

Figure 2 is an enlarged elevational view of the interior mechanism of the dispensing device.

Figure 3 is a further enlarged view of a portion of the automatic control mechanism shown partly in vertical section and in position ready to open the air valve.

Figure 4 is a View of a portion of the mechanism shown in Figure 3 showing the air control valve release mechanism in the p releasing position.

Figure 5 is a full sia vertical sectional view of the control valve mechanism showing the compressed air supply for elevating the gasoline to the bowl.

Figure 6 is a view similar to Figure 5 showing the air valve opened to direct come pressed air to the bowl supply tank.

In the dispensing of gasoline a great variety of pumps are used and the present invention has to do with the visible bowl type. The form shown is compressed air operated,"the gasoline being forced upwardly to the bowl from a small tank of slightly greater capacity than the bowl, said small tank being fed from the main reservoir.

In the construction illustrated, the tank 1 is the main supply and the tank 2 is fed by gravity from the tank 1 through the pipe 3, a check valve 3x being arranged therein.

An air pipe 4 leads to the tank 2, being fed from la suitable pressure supply and controlled by a valve mechanism hereinafter described: A

When the compressed air is directed through the pipe 4 the gasoline in the tank 2 is orced up through the pipe 5 to the bowl 6.

Some well known forms of pumps have this air supply controlled by a hand operated valve but it is the purpose of this invention to make the control of the air automatic.

In the construction hereinshown an overflow pipe 7 extends upwardly within the bowl to the level of the highest graduation mark thereon and when the bowl is filled to this level any further quantity of gasoline entering the bowl spills down the pipe 7 and is conducted to a cylindrical casing 8 which is provided with an enlarged portion 9 in the side walls of which are arranged the ports 10.

A funnel-shapedk receptacle 11 is connected to the flanged bottom of the portion 9 and conducts the gasoline flowing thereintoto the pipe 12 which returns to the main tank 1. Within the cylinder 8 is arranged a piston 13 in the form of a flat plate provided with arallel guiding lugs 14 extending upwardly therefrom to engage the wall of the cylinder in sliding contact.-

^ Then the gasoline overflows into the pipe `7 fro1n the bowl it falls upon the piston 13 and immediately depresses same. The piston is connected with a rod 16 extending upward- 1y through the stutling box 17 on the top of the cylinder and this rod is connected to a counterbalance lever 18 by a flexible cord 19. The counterbalance of the lever 18 normally holds the piston at the upper end ofthe cylinder but when the gasoline overflowing mto the pipe 7 falls upon the piston, the counterbalance isove'rbalanced and the piston drops down until the plate enters the enlarged portion 9 when thebody of gasoline bearing on the plate flows into the ports 10 and is 'discharged into the' funnel shaped receptacle 11 and instantly clears the piston. l

Drain holes 20 are arranged in the piston to allow any gasoline which might otherwise be trapped on top of the piston to escape.4

A stop member 21is secured on the rod 16, preferably where it connects with the cord 19. A forked lever 22 having its forked end 23 straddling the piston rod 16 is pivotally suspended from a jaw end 24 on the lower end of a rod 25 which isslidably supported by a bracket 26 which bracket also supports the lever 18. v

' The upper end of this rod 25 is connected to a lever 27 pivotally mounted on a bracket 28, said lever having a fork 29 at its outer end to receive and support the nozzle end of the dispensing tube.

The

brackets

28 and 26 are supported upon a pipe 30 which connects with the bottom of the bowl and communicates through the 31 and meter 32 with the flexible dispensing tube 33.

A stop valve 34 is arranged below the T 31 and the pipe continues below said stop valve and connects with the drain pipe 12 leading from the overflow from the bowl. This stop valve may be opened to drain out.

the gasoline from the bowl in the eventvof fire' pump is to be left unguarded.

or when the Connected to the lower end of the forked lever 22 is a toggle member 35 which is pivotally secured to aT pipe connection 36, the' laterally extending portion of which is connected by a flexible tube 38 to the pipe 4 which leads to the elevating tank 2.

The toggle member 35 is provided witha laterally extending lug 39 which is engagedvby a set screw 40vthreaded into a correspondingly arranged lug 41 extending from the lever 22. ByA the adjustment of this set screw the pivot of the toggle joint 43 between the lever 22' and member 35 is adjusted in its relation to its alignment between the pivotal connection of the lever 22 in the forked supporting member 24 and the pivotal connection of the toggle 35 to the T pipe 36.

It will be seen that this adjustment may be made very sensitive so that a very smallquantity of gasoline falling upon the top of the piston 13 will break the toggle joint between the lever 22 and member 35 and cause it to assume the position as illustrated in Figure 4.

The T connection 36 hassecured to its underside a hollow stem 44 which extends into a cylindrical chamber 45. j The stem is formed with a flange 46 which slides in the chamber 45 and a tube 47 is secured in said flange and extends through an opening in the bottom wall 49 of the chamber 45.

A spiral compression spring 48 encircles the tube 47 and engagesjhe flange 46 exerting an upward pressure to hold the tube in the raised position shown in Figure 5.

i The tube extension 47 projects into a charnber 50 which is connected by a pipe 51 with the overflow ply tank 1.

The bottom end of the tube 47 is ladapted when depressed to engage a valve 52slidably arranged in a recess at the underside of the chamber 50.

The valve 52 has a central passage 53 opening through the top and provided with holes 54 opening laterally from the lower end of the stem.

A casing 55 is secured to thebottom side of the casing containing the chamber 50 and a rubber or leather gasket 56 is secured between these casings and encircles the stem of the valve 52.

The lower end of the stem of the valve 52 is threaded into a valve 57 which is heldin contact with the gasket 56 by a coil compression spring 58.

The lower end of the casing 55 is connected with a pipe 59 leading from a suitable compressed air supply and is provided with a stop valve 60 by means of which the air may be shut olf. In the operation of this device, the gasoline dispensing tube 33, which is connected with the bottom of the bowl in the manner described is normally supported by the forked lever 29 and the toggle joint comprisingthe forked lever 22 and the toggle 35 is broken as illustrated in Figure 4.

When a customer is to be served the valve end of the tube 33 is lifted from the fork and said fork is pulled upwardly by the spring 61, thus straightening thetoggle and bringing the forked end of the'lever 22 close to the stop 21 ofthe piston rod 16.

When the required amount of gasoline is taken from the bowl the dispensing tube is returned to the lever holder. The weight of the tu-be and valve swings the lever 27 downwardly pushing down upon the rod 25 against the lever 22 and through the toggle 35 the T pipe 36 with its hollow stem is pipe 12 leading to the main supdepressed until the inner end of the extension 47 connects with the valve 52, first making an air tight joint therewith. The valve is then depressed against the pressure of the spring 58 and moves the valve 57 from its seating against the gasket 56'. This allows compressed air from the compressed air( supply to flow through the hollow stem of the valve 52 and from thence the air flows through the pipe extension 47, hollow stem 44, T pipe connection 36 and flexible tube 38 to the pipe 4 which conducts the air to the tank 2 to elevate the gasoline therefrom through the pipe 5 to the bowl.

Upon the gasoline rising to the level of the overflow pipe 7 which is in line with the highest dimension of measurement marked on the bowl, the gasoline flows down the pipe 7 into the cylindrical casing 8 and forces the piston 13 downwardly, bringing the stop 21 into engagement with the fork of the lever 22 which then swings on its pivot to break the joint of the toggle connection tothe air valve. The spring 48 encircling the tube 47 lifts the extension 47 upwardly, first allowing the closing of the air Valve 57 and continuing upward it breaks the connection between the valve 52 and the tube 47.

The flow of compressed air to the auxiliary supply tank is immediately cut ott' and the pressure of air inthe tank 2 flows back through the pipe 4, tubev38 and tube 47 to the chamber 50 from whence it escapes through the pipe 51 back through the overflow pipe 12 to the main tank 1 which is vented.

Immediately following the depression of the piston the overflow is released and re-.

turns to the main tank passing through the funnel 11 which allows the rapid escape of the fluid so that the action of the piston will not be impeded. When the overflow ceases the counterweight immediately returns the piston and the device is ready for another operation.

The operation of the device is entirely automatic and is very rapid. The instant the dispensing pipe is hung up the, air valve is opened and the supply in the bowl is replenished. I

It will of course be understood that when the air pressure is applied to the tank 2 the gasoline is prevented f-rom returning to the main tank by the check valve 3".

The supply pipe 5 leading from the tank 2 to the bowl is provided with a hand operated pump 62 which may be used in the event of the air supply failing.
